,application mea september 13, 192e. serial No. 134,979.-

This invention relates to internal combustion engine feeds and hasspecial reference to such a device for the automatic vcontrol of anauxiliary air supply for the intake of such engine. j

The principal object is to p-rovide simple, g automatic means for thecontrol ofsuch auxiliary air supply.

Another object is to provide simple means of moistening such auxiliaryair supply, the beneits of both of which objects are well known to thoseversed in the art.

Other objects and advantages of the invention will appear inthefurtherdescription. Referring now to the accompanying drawing, forming part ofthis application, and wherein like: reference characters indicate likeparts:

`invention applied thereto; and

Figure 2 is an enlarged perspective view of the automatic controllingmechanism.

l-represents the engine, 2 the fan for same, and' the intake manifold.Just above the central portion of the manifold and supported upon asuitable pipe connection indicated at 4 upon the side thereof is thehorizontally disposed valve 5. firepresents the stem of the valve bywhich passage there! through is controlled, andupon the outer end ofthis steml is securely attached in any desired manner, as for example bytwo jam nuts, the outer oneof which is illustrated at sideanges 9 and 10thereupon. This vane is disposed above the valve soas to face the fan 2of the engine, sothat air coming from,

the fan when the latter is in operation will cause vthe vane to rockbackwardly therefrom and thus openvthe valve 5.

Upon the opposite end of the valve 5 to that from which the stem 6protrudes is the necessary feed ypipe connection including the nipple11, and upon which is mounted in close proximity to the valve thev thin`flat arm 12, projecting both forwardly and rearwardly of the valve, theformer being considerably more extensive than the later and providedwith a series of small holes along its uppermost edge as indicated at13, these being for the purpose of receiving one end of a contractilehelical spring 14, the opposite end of which is similarly engageablewith the flange 9 of Figure 1 is a side elevation of the upper' 7, theiiat `wind' controlled vane 8, having the wind vane, it alsobeingprovided with a series of holesindicated at 15, such series, p

as is obvious, being for any desired adjustment of the spring in respectto the force i and side of thefan employedupon the engine to which-theattachment'may be lixed.

Theair supply pipe is indicated at 16 and leads above and down intov thetop of the water tank 17 ii'xed'to the dash board 18.of the automobile,or, as is obvious, any other convenient support adjacent the engine. `Inthis instance the tank 17 is preferably in the formof a glass container,for example like a fruit jar, the end of the pipe16 being thereof4but'not into the liquid within the v,attached to and protruding throughthe cover tank,l and this liquid vmay be either water or any otherfluidv known to be beneiicial vfor use in the engine. The air supplypipe to i' .the tank 17 is illustrated at 19 .and is preferably of finverted U-'shape with one end openV to the atmosphere and the'other endterminating within the tank 17 adjacent the suction end,v of the pipe16, but to thisy endr of the air supply pipe is attached preferably aflexible tube 20 leading to the bottom of the tank so that air whendrawn into the tank must ypassv through the liquid therein, and such airwhen withdrawn from the tank through the pipe 16 will become more orless impregnated with the nliquid in the tank,

which, if consisting Mof plain water, will simply `add moisture to Atheair, asy it is drawn into the manifold of the engine. l

From the above it is evident that when an engine, thus equipped isstarted theac tionof the air thrust'backwardlyv--by the fan will causethe vane 8 to lean backwardly in respect of course to the tension of thespring 14,'and thus correspondingly'open the valve 5, permitting of thefunctioning ofthe aux-y iliary air supply to the manifold, Aandprovision isV made against opening too far of the 'valve by the loweredge yof thevane 8 contacting the rearward stepped projection of the arm12. It will be noted that thefup-y per edge of this arm, intermediatevof its stepped portions, is inclined, as at 21, so that the springlimay not draw the vane to anabnormally` closed position, and which willassure its .operation at all times.

Having thus described my invention,l what i I claim and desire to secure1by Letters Patj ent, is
